IT security techniques — Non-repudiation — Part 1: General
This part of ISO/IEC 13888:2004 serves as a general model for subsequent parts specifying non-repudiation mechanisms using cryptographic techniques. The goal of the non-repudiation service is to generate, collect, maintain, make available and verify evidence concerning a claimed event or action in order to resolve disputes about the occurrence or non-occurrence of the event or action. There are…
